What is CVE-2026-15601?

The Kirki Page Builder plugin for WordPress is susceptible to a path traversal vulnerability that can occur through its extract_zip_file function. This flaw affects all versions up to and including 6.0.13, allowing authenticated users with custom-level access or higher to potentially write arbitrary files on the server. The vulnerability arises from the improper handling of a user-supplied app src value, which is used to construct download URLs. As a result, crafted ZIP files could be extracted in unintended directories, facilitating remote code execution by malicious actors.
